The aim of the present invention is a manufacturing process for assembly parts ( ) for the manufacture of elements of chemical devices ( ), comprising the fixation of an anticorrosion metallic coating ( ) on an unprocessed assembly part ( ), by means of an operation comprising a brazing operation under a controlled atmosphere and, possibly, the shaping of the coated part ( ), by plastic deformation. The brazing temperature is preferentially less than approximately 750&deg; C., and more preferentially between 600&deg; C. and 720&deg; C. The process according to the invention makes it possible to fix solidly on a steel plate an anticorrosion coating with a thickness less than 1 mm.

Manufacturing process for an element of a chemical device comprising a support part in metal and an anticorrosion metallic coating

The aim of the present invention is a process for manufacturing a plated product ( ) comprising a support part in steel ( ) and an anticorrosion metallic coating ( ), characterized in that the anticorrosion coating ( ) is fixed on the support part ( ) by controlled-atmosphere brazing, in particular by vacuum brazing. The process according to the invention makes it possible to fix solidly an anticorrosion coating with a thickness smaller than 1 mm on a steel plate.
